The BEZARES 905213 (models BZ‑101, BZ‑102, BZ‑103) is a cabin‑mounted pneumatic valve control unit designed for heavy‑duty truck hydraulic systems. It provides pneumatic actuation of 1, 2, or 3‑way hydraulic circuits, enabling the driver to engage the Power Take‑Off (PTO) and operate tipping valves or other hydraulically‑driven equipment directly from the vehicle cabin. The integrated warning light provides a clear visual indication that the PTO is engaged, reducing the risk of accidental vehicle movement with the PTO active—a critical safety feature for work trucks operating in construction, mining, and municipal service environments. The unit is supplied as a complete installation kit, including the pneumatic control lever (red handle), air hose, brass fittings, and all required mounting hardware.

1/2/3-Way Pneumatic Control — One Kit, Multiple Hydraulic Circuit Types

• 1‑Way Control (BZ‑101): For simple single‑action hydraulic circuits where the PTO is engaged and disengaged via a single pneumatic signal. Typical application: engaging a hydraulic pump for a basic tipping function.
• 2‑Way Control (BZ‑102): For double‑action circuits where two pneumatic signals control the directional flow of hydraulic oil. Typical application: controlling both the raise and lower functions of a tipping cylinder.
• 3‑Way Control (BZ‑103): For more complex circuits requiring three pneumatic channels to manage multiple hydraulic functions simultaneously—such as a tipping trailer that requires independent control of the main lift cylinder, a stabilizer leg, and a tailgate lock.
• Slow Descent and Rapid Descent Modes: The pneumatic controls support configurable descent speeds—slow descent for precision load placement and rapid descent for high‑cycle operations where fast tipping cycles reduce turnaround time.

Integrated Warning Light for PTO Safety

• Visual PTO Status Indication: The built‑in warning light illuminates whenever the PTO is engaged, providing an unambiguous visual signal to the driver and to ground crew working around the vehicle. This is a fundamental safety requirement for compliance with workplace safety regulations in quarrying, civil engineering, and waste management operations.
• Prevention of Accidental PTO Engagement: When the PTO is not intended to be active—during highway driving or when loading/unloading personnel are near the vehicle—the warning light provides immediate confirmation that the system is disengaged. If the light remains on, the driver knows to check the PTO switch position before moving the vehicle, preventing the dangerous combination of PTO operation with vehicle movement.

Complete Installation Kit — Everything Included

• All Components Supplied: The 905213 kit includes the pneumatic control lever with distinctive red handle, a length of air hose for connecting to the vehicle's pneumatic system, brass fittings for leak‑free connections, and all necessary mounting bolts, nuts, and washers. This eliminates the need to source individual pneumatic components and ensures compatibility between all parts of the control system.
• Standard Pneumatic Fittings: The brass push‑in and threaded fittings are compatible with standard industrial pneumatic tubing (typically 6 mm or 1/4 inch OD), allowing the unit to be connected to the vehicle's existing compressed air supply without adapters. Small pneumatic accessories—seals, O‑rings, and protective caps—are also included, reducing the likelihood of installation delays due to missing components.
• Lightweight Design (0.5 kg): At only 0.5 kg, the 905213 places minimal additional load on the cabin dashboard or control panel mounting point. This is significant in heavy‑duty trucks where vibration fatigue can cause mounting failures of heavier control assemblies over time.

Applications

• Tipper trucks for construction, mining, and quarrying: cabin‑mounted PTO engagement and tipping control with warning light for ground‑crew safety
• Municipal service vehicles (garbage compactors, road sweepers): pneumatic control of auxiliary hydraulic equipment from the driver seat
• Agricultural trailers requiring hydraulic tipping or auger control: 1‑way or 2‑way pneumatic actuation from the tractor cabin
• Any commercial vehicle application where a complete, pre‑assembled pneumatic PTO control kit with integrated safety warning reduces installation time and improves operator safety compared to sourcing individual components
